| Abstract | ||
| Two field trials were carried out under sprinkler irrigation system with wheat crop at the Desert Development Center (DDC), El-Khartoum Village, American Univ. Cairo, Egypt, during 1996 - 1998 seasons, to evaluate the effects of pre-irrigated with tillage or contact herbicide (paraquat), non pre-irrigated sowing and twenty herbicidal treatments on wheat productivity. The herbicidal treatments are included tribenuron-methyl, metosulam, chlorosulfuron, isoproturon, fenoxaprop-ethyl, tralkoxydim, diclofop-methyl, flamprop-isopropyl, clodinafop-propargyl and imazamethabenz-methyl. Pre-irrigation with tillage or contact herbicide gave higher biological and grains yield, number of grains / spike, number of spikes / m2, 1000-kernel weight, plant height, spike length and number of spikelets / spikes in the first season. On the other hand, biological and grains yield significantly increased with two pre-irrigated systems compared with non pre-irrigated one, in the second season. Most of the herbicidal treatments significantly increased wheat biological and grains yield, number of spike / m2 and number of grains / spikes in both seasons. However, the high values were obtained with the combinations between grassy and broadleaves herbicides. | ||
